Transmute is a free, open-source, self-hosted file converter and compressor that runs entirely on your own hardware via Docker. It converts and compresses images, video, audio, documents, spreadsheets, data files, 3D models, subtitles, fonts, and more across thousands of format combinations, with no file size limits, no watermarks, and complete privacy since nothing leaves your server. I personally use it every day on my NAS in my homelab for routine conversions and compressions. In this step by step guide I will show you how to install Transmute on your Synology NAS using Docker & Dockhand.

💡Note: This guide works perfectly with the latest Transmute v2.0.0 release.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 9

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://synology-ip-address:3313 Create your administrator account. Click Create Admin Account. Follow the instructions in the image below.
